From the equation
![{x}^{2} - 10x + 25 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%2010x%20%2B%2025%20%3D%200)
We can see that 25 is 5 × 5, and 10 is 5 + 5, so the equation simplifies to
![(x - 5)(x - 5) = 0 \\ {(x - 5)}^{2} = 0](https://tex.z-dn.net/?f=%28x%20-%205%29%28x%20-%205%29%20%3D%200%20%5C%5C%20%20%7B%28x%20-%205%29%7D%5E%7B2%7D%20%20%3D%200)
which then we use to set each parentheses to equal 0
![(x - 5) = 0 \\ x = 5](https://tex.z-dn.net/?f=%28x%20-%205%29%20%3D%200%20%5C%5C%20x%20%3D%205)
Since both parentheses are the same, there is only one solution: C. 1 real number solution

Answer:
0.2755
Step-by-step explanation:
We intend to make use of the normal approximation to the binomial distribution.
First we'll check to see if that approximation is applicable.
For p=10% and sample size n = 500, we have ...
pn = 0.10(500) = 50
This value is greater than 5, so the approximation is valid.

The mean of the distribution we'll use as a model is ...
µ = p·n = 0.10(500)
µ = 50
The standard deviation for our model is ...
σ = √((1-p)µ) = √(0.9·50) = √45
σ ≈ 6.708204

A continuity correction can be applied to better approximate the binomial distribution. We want p(t ≤ 9.1%) = p(t ≤ 45.5). For our lookup, we will add 0.5 to this limit, and find p(t ≤ 46).
The attached calculator shows the probability of fewer than 45.5 t's in the sample is about 0.2755.
477 yards is the answer simply because 1431 ft is equivalent to 477 yards....
